1 answer:
Answer:
Th proportion of satisfied customers is
Step-by-step explanation:
Although 1,000 surveys were send, we may consider our sample is only made by the 823 surveys returned.
Out of the returned surveys (n=823), 635 people said they were satisfied with the restaurant.
Then, the p-hat (proportion of satisfied people) of this sample is calculated as:
If we consider as the sample size all the surveys sent, and assuming the surveys not returned belong to non-satisfied customers, the proportion of satisfied clients is:

Answer:
True
Step-by-step explanation:
Even though we cannot see the parallelogram, we can assume the dimensions of the original parallelogram is height= 3 and base= 6.
If we double the dimensions, we get:
height=6 band base=12.
The area of the original parallelogram is 18 square units.
The area of the enlarged parallelogram is 6×12= 72 square units.
Now,
Hence, the area of the larger parallelogram is 4 times more than the original.
You can observe that every next term is computed by adding 4 to the previous one.
This implies that the difference between consecutive terms is always 4, and this is an arithmetic sequence.
In order to find the explicit equation, we can explore the pattern:
So, as you can see, we have
If 109 is a term of the sequence, there must exist a natural number n such that
So, 109 is not a term of the sequence.
